specification forining part of Letters Patent No. 21,054, dated July 27, 1858.

To all witam it may concern:

Be it known that we, EDWARD A. RAYMOND and CHARLES RoB1TA1LLE,of Brooklyn, in the county of Kings and State of New York, have invented, made, and applied to use certain new and useful Improvements in Repeating Fire-Arms; and we do hereby declare'that the following is a full, clear, and exact description of the construction and operation of the same, reference being had to the annexed drawings, making part of this specification, wherein- Figure 1 is a side elevation of our improved fire-arm with the Cap-plate removed. Fig. 2 is an elevation of the breeches or ehambers at the rear end. Fig. 3 is an end view of the barrel and latch receiving the loading-lever, and Fig. 4 is an inverted plan of said loading-lever and the parts attached.

Similar marks of reference denote the same parts.

In Letters Patent granted to O. S. Pettengill on 22d July, 1856, a repeating-arm is shown in which the ehambers are revolved by a lever having a looking-pin at the end thereof, which, projecting into a hole at the rear of the chambers each successive discharge, holds the breech or chamber to be fired properly in line with the barrel, and in moving this lever a separate and detached mainspring is strained to discharge the hammer.

Our invention is an improvement on the aforesaid patent of Pettengill, and relates to a manner of working the said mainspring and lever, so as to perform all the functions required of them; also, to a manner of cansing the end of the lever itself to lock and hold the ehambers with the proper one exactly on the line of the barrel, thereby dispensing with the hinged looking-pin of Pettingill, which isfound practically to be nnreliable, because it often beconies wedged improperly into the rear of the ehambers, particularly when the parts become fouled by the explosion.

In the drawings, ais the stock. bis the barrel, connected together with the straps c, between which the ehambers (Z revolve on the center-pin c. j'is the trigger-guard, and g is the trigger on the pin 1. IL is the lever to revolve the ehambers, set with an elongated hole over the fulcrum 2, and formed as a part of the mainspring i, which is connected by the bridle 3 to the hummer k, moving on the pin 1. lis the sear of the hammer, and 5 is a spring taking into the recesses 8 of the ehambers to prevent them being revolved in the wrong direction. On pulling the trigger g the upper part, 4, takes the roller 6 on the lever h, elevating said lever, and the point 7 thereof, taking one of the recesses 8, gives apartial rotation to the ehambers, and as the lever h comes up into the position shown in Fig. 1 the ehambers become blocked by the end of said lever, so that the chamber to be discharged is on the line of of the lever h rising vertically in the line shownby the dots in Fig. 2, when the said part 7 reaches the apex of said triangular recess there can be no more motion of the ehambers either way so long as said lever h is fully elevated. In the act of using the lever h the opening between the said lever and its mainspring i has been increased, so that the moment said lever h reaches its extreme elevation the trigger g disengages the sear l, and the spring i, through the bridle 3, propels the ham mer k and explodes the cap and the chamber which is on the line of the barrel b, an opening being provided in the recoil-shield x for the passage of the end of the hammer lc. Upon releasing the trigger g the spring m comes into operation, which causes the lever h to descend, and the roller 6, passing down the part 4, causes the trigger g to move forward, and the end 7 of the lever h slides down the incline from one recess Sto the next, the elongated hole for the pin 2 allowing of this motion, and then the roller 9 on the end of the spring m, rolling down the incline 10 on the lever Iz, causes the end 7 to be projected into the next recess 8, and the spring fi, moving with the leverh, draws back the hamrner k, the sear lfalls into its notch on` the tumbler of said hammer, and the parts are ready for` use, as before.

The pin c is held in place by means of a spring, ll, attached at one end to said pin e and at the other end provided with a crosspiece, and said 'spring occupies a parallel recess in the under side of the barrel b, and the end of said spring, taking against the side of a crossgroove in said barrel or a projection thereon, forms a resistance to keep said pin e in place While the lever 'n and rammer o are being used to ram the charges in the Chamber d. 12 is the fulorum of said lever n, and 13 is the joint-between the lever n and raminer. By raising the spring 11 out of the slot the center-pin e can be withdrawn for removing the ohambers d, and there are no separate screws or pieoes that are liabie to be lost.

The lever n is of a length to extend as far as the end of the barrel b, and is made with a split in its center, so as to form a double spring, and the sides of this lever n are notohed to fit the latch 14, (see Fig. 3,) so that When pressed into said lateh the sides of the levern spring together, and when said lever is to be turned down for use the grasping of the same between the fingers and thu mb com presses the sides and disconnects the lever from the latch. We do not elaim any part of the invention upward movement, for the purpose and as specified.

In Witness whereof we have hereunto set our signatures this 5th day of June, 1858.
